    Abstract: A mechanochemical actuator capable of producing mechanical energy in response to stimuli such as change in pH or salt concentration comprises a polymer composed of hydrophobic polymeric segments and hydrophilic polymeric segments, said hydrophobic polymeric segments being derived from either (1) a copolymer formed from a hydrophobic polymerizable monomer and a polymerizable monomer capable of forming hydrophilic polymeric segments after copolymerization with said hydrophobic polymerizable monomer and, if necessary, polymer modification, or (2) a modified product of said copolymer. Examples include a saponified product of an ethylene-acrylic acid copolymer or butadiene-acrylic acid copolymer, or a maleic acid-modified product of EPDM or polybutadiene, or a sulfone-modified product of EPDM or polybutadiene. The actuator can be used in small machines (eg robots), medical appliances and prosthetic devices.
